Description

Technical Field

[0001] The utility model belongs to the technical field of slide rails, and in particular relates to a sitting type slide rail structure. Background Art

[0002] Slide rails are a type of sliding tool that is widely used in daily life. They are usually used to connect two objects that can move relative to each other, such as drawers, cabinet servers, etc.

[0003] The more common three-section steel ball slide rail is installed on the drawer-type device and is used for free pulling out and pushing back of the drawer-type device. Taking the drawer as an example, the three-section steel ball slide rail usually includes an outer slide rail, a middle slide rail and an inner slide rail. The outer slide rail is fixed on the support frame, and the inner slide rail is fixed on both sides of the drawer. The middle slide rail is connected between the outer slide rail and the inner slide rail as a bearing slide rail to extend the range of motion of the drawer, and allows the middle slide rail and the inner slide rail to slide back and forth relative to the outer slide rail along the axis direction of the outer slide rail, so that the drawer can be freely pulled out or pushed back through the slide rail.

[0004] With the advancement of technology, as an important component, the slide rail has higher and higher requirements on its load-bearing capacity. The current three-section steel ball slide rail is usually a side-sliding structure with poor load-bearing capacity. At the same time, the operation of lubrication and maintenance of the steel balls is also more complicated after long-term use.

[0005] Based on this, the applicant considered designing a seat-type slide rail structure. Utility Model Content

[0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide a seat-type slide rail structure.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A sitting type slide rail structure includes a first rail and a second rail, wherein the second rail is cooperatively arranged above the first rail, a ball is arranged between the first rail and the second rail, the second rail is slidably connected to the first rail through the ball, a lubrication groove is arranged on the top surface of the second rail, the lubrication groove can be located above the ball when the second rail overlaps with the first rail, and a plurality of through holes are opened on the bottom surface of the lubrication groove.

[0009] Compared with the prior art, the seat-type slide rail structure of the utility model has the following advantages:

[0010] By setting the first rail, the second rail, the lubrication groove and the through hole, base-type bearing is achieved through the second rail, and lubricating oil can be added to the ball for maintenance through the lubrication groove and the through hole. The load-bearing capacity is strong and the ball is easy to lubricate and maintain, avoiding the need to lubricate the balls on the upper and lower sides of the rail at the same time during side-sliding maintenance, which makes the lubrication operation more complicated.

[0011] The above-mentioned sitting type slide rail structure has the advantages of simple structure and easy implementation, and the cost of use is low, which can improve the efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] When implementing: Figure 1-3 As shown, the sitting type slide rail structure includes a first rail 100 and a second rail 200, the second rail 200 is cooperatively arranged above the first rail 100, a ball 300 is arranged between the first rail 100 and the second rail 200, the second rail 200 is slidingly connected to the first rail 100 through the ball 300, and a lubrication groove 210 is arranged on the top surface of the second rail 200. The lubrication groove 210 can be located above the ball 300 when the second rail 200 overlaps with the first rail 100, and a plurality of through holes 220 are opened on the bottom surface of the lubrication groove 210.

[0022] Compared with the prior art, the seat-type slide rail structure of the utility model has the following advantages:

[0023] By setting the first track 100, the second track 200, the lubrication groove 210 and the through hole 220, base-type bearing is achieved through the second track 200, and lubricating oil can be added to the ball 300 for maintenance through the lubrication groove 210 and the through hole 220. The load-bearing capacity is strong and the ball 300 is easy to lubricate and maintain, avoiding the need to lubricate the ball 300 on the upper and lower sides of the track at the same time during side-sliding maintenance, and the lubrication operation is relatively complicated.

[0024] The above-mentioned sitting type slide rail structure has the advantages of simple structure and easy implementation, and the cost of use is low, which can improve the efficiency.

[0025] In this embodiment, Figure 1-3 As shown, the longitudinal section of the through hole 220 is in the shape of an inverted trapezoid.

[0026] In this way, the radius of the through hole 220 set close to the lubrication groove 210 is large, which can better pass the lubricating oil dripped into the lubrication groove 210. The radius of the through hole 220 close to the ball 300 is smaller, so that the speed of the lubricating oil dripping into the ball 300 is slower and the lubrication is more uniform.

[0027] In this embodiment, Figure 1-3 As shown, the top surface of the first track 100 is provided with a rolling groove 110, and there are multiple balls 300, which are arranged side by side in the rolling groove 110. The second track 200 has a sliding groove opening downward, and the second track 200 abuts against the multiple balls 300 through the bottom surface of the sliding groove.

[0028] In this way, the balls 300 are arranged to abut against the sliding grooves, so that the second track 200 is mounted on the first track 100 through the balls 300, so that the second track 200 can slide on the first track 100 more stably.

[0029] In this embodiment, Figure 1-3 As shown, the length of the lubrication groove 210 is consistent with the length of the rolling groove 110 .

[0030] In this way, when the second track 200 overlaps with the first track 100, the lubricating oil added to the lubricating groove 210 can better fall into the rolling groove 110 through the through hole 220 to lubricate the ball 300, thereby preventing the lubricating oil from falling to other places and having no effect.

[0031] In this embodiment, Figure 1-3As shown, the second rail 200 includes a docking end 400, and the docking end 400 includes two clamping arms 410. A clamping groove 420 is arranged between the two clamping arms 410. A clamping cavity 411 is opened in each of the two clamping arms 410. Both of the two clamping cavities 411 have openings, and the directions of the two openings are arranged opposite to each other. A clamping mechanism is arranged in each of the two clamping cavities 411.

[0032] During implementation, the drawer-type device installed on the second track 200 is provided with a clamping body corresponding to the clamping slot 420 , and the clamping body can extend into the clamping slot 420 .

[0033] In this way, by providing two clamping arms 410 and the clamping mechanism, the second rail 200 can be quickly clamped to the drawer-type device to be installed on the second rail 200 through the clamping mechanism.

[0034] In this embodiment, Figure 1-3 As shown, the locking mechanism includes a rotating buckle 430 and a spring 440. The middle part of the rotating buckle 430 is rotatably installed in the corresponding locking cavity 411. The rotating buckle 430 includes a toggle end and a locking end. One end of the spring 440 is connected to the locking end, and the other end is connected to the bottom wall of the locking cavity 411. When the rotating buckle 430 is in a closed state, the toggle end is located in the locking cavity 411, and the locking end extends into the locking groove 420 through the corresponding opening.

[0035] During implementation, the spring 440 is a compression spring 440 , and when the rotating buckle 430 is in a closed state, the spring 440 is in a natural state.

[0036] In this way, by providing the rotating buckle 430 and the spring 440, the rotating buckle 430 can seal the engaging slot 420 when closed, and can allow the engaging body on the drawer-type device to squeeze the rotating buckle 430 into the engaging slot 420 for engaging, and the structure is relatively simple.

[0037] In this embodiment, Figure 1-3 As shown, a toggle post 450 is provided on the toggle end, and a toggle track 460 is provided on the lower side wall of the clamping cavity 411 . The toggle post 450 can pass downward through the toggle track 460 and protrude out of the clamping cavity 411 .

[0038] In this way, by setting the toggle column 450 and the toggle track 460, when it is necessary to remove the drawer-type device from the docking end 400, the toggle column 450 can be toggled to change the rotating buckle 430 to the open state, and then the drawer device can be taken out. The structure is relatively simple and the reliability is high.

[0039] The above are only preferred implementations of the present invention. It should be pointed out that a number of modifications and improved technical solutions made by those skilled in the art without departing from the technical solution should also be deemed to fall within the scope of protection required by the claims.
